您好

我希望在点击“Hello”时将此弹出窗口显示为中心

Answer 1

要在中心打开，您需要使用屏幕的宽度和高度。单击时打开，只需将其绑定到window.onload：

        function open1() {

            var left = (screen.width - 400)/2,
                top = (screen.height - 200)/2,
                settings = 'height=200,width=400,top=' + top + ',left=' + left;

            window.open('http://www.pageresource.com/jscript/jex5.htm','popUp',settings); 
        } 

        window.onload = function (){
            document.getElementById("openPopup").onclick = open1;
        }

Answer 2

创建ID为“open”的HTML元素，并将此脚本嵌入到文档的头部：

function open1() {

    var w = 400, // width of your block
        h = 200, // height of your block
        l = (screen.width - w)/2, // block left position
        t = (screen.height -h)/2; //block top position

    window.open('http://www.pageresource.com/jscript/jex5.htm','','height=' + h + ',width=' + w + ',top=' + t + ',left=' + l);
}

window.onload = function() {
        document.getElementByID("open").onclick = open1;
}

显示新窗口弹出中心
